Abstract

In this paper author has purposed improved LSB substitution method for hiding text information written in text file into color image. In this method each character of secret message including special character such as space, enter, <,?, $etc. is converted in ASCII code then each value is converted in 8 bit binary number. Each bit of each character is embedded in last LSB of each pixel of cover image. Since only last bit each pixel of cover image get changed, this method is capable of producing a secret-embedded image that is totally indistinguishable from the original image by the human eye. This method is applied to cover image of bitmap and jpeg format to show that this technique is suitable for both format.
